Ultrathin initiated chemical vapor deposition polymer interfacial energy control for directed self-assembly hole-shrink applications

Published in Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2019

My contributions to this paper were using Monte Carlo simulations of block copolymer self-assembly to find defect structures that correlated well with the ones observed experimentally, highlighting the validity of the 3D imaging technique used by the experimentalists.

Influence of Homopolymer Addition in Templated Assembly of Cylindrical Block Copolymers

Published in ACS nano, 2019

My contributions to this paper were using Monte Carlo simulations of block copolymer self-assembly to build phase diagrams of block copolymers confined in elliptical templates. I helped demonstrate that there is a certain window of concentration of homopolymers that stabilize well-separated double cylinder structures in such confinements. My simulations also helped verify that the homopolymer preferentially segregates to certain regions of the film, lending credence to the experimental hypothesis of the mechanism of the homopolymer stabilization of a doublet structure.

Mechanisms of Directed Self-Assembly in Cylindrical Hole Confinements

Published in Macromolecules, 2018

This paper uses the string method to investigate the mechanism of the formation of through film cylindrical morphologies in cylindrical confinements during block copolymer directed self-assembly. We find that the assembly process most critically depends on the interaction between the polymer and the confinement sidewall.

Studying the effects of chemistry and geometry on DSA hole-shrink process in three dimensions

Published in Emerging Patterning Technologies 2018, 2018

My contributions to this paper include simulations of block copolymer directed self-assembly in the "hole-shrink" process, demonstrating that our coarse-grained simulations predict the same morphologies observed through direct imaging of 3D structures from experiments.
